I’m currently writing a program where I have a string of methods all set

0

I’m currently writing a program where I have a string of methods all set up basically identical. If they’re given i = 1, they’ll return the price of the product times the quantity ordered. Otherwise, they simply returned the quantity ordered. Whenever I attempt to compile it, however, the compiler says that the brackets are missing return statements. I’ve gone through the code several times and I don’t see anything overtly wrong in the syntax. Any guesses as to why this is happening?

Thank you for any help.

There is no return guaranteed due to your try-catch blocks.

You might want to return a sentinel of 0 or -1 to show this.

An example that may make this more clear:

double acidPopsTotal(int i) {
    if (i == 1) {
        try {
            return (5.95* (Integer.parseInt(acidPopsTF.getText())));
        } catch (NumberFormatException e) {
            //Missing return - compile error
        }
    } else {
        try {
            return Integer.parseInt(acidPopsTF.getText());
        } catch (NumberFormatException e) {
            //Missing return - compile error
        }
    }
}
